Field wiring must comply with the National Electric
Code (C.E.C. in Canada) and any applicable local
code.
Power Wiring
It is important that proper electrical power from a
commercial utility is available at the compressor
contactor. Voltage ranges for operation are shown
below.
VOLTAGE RANGES (60 HZ)
Install a branch circuit disconnect within sight of
the unit and of adequate size to handle the starting
current see lectrical Data on page 5.)
Power wiring must be run in a rain-tight conduit.
Conduit must be run through the connector panel
below the access cover (see page 6) and attached
to the bottom of the control box.
Connect power wiring to line-voltage lugs located
in the outdoor unit electrical box. (See wiring
diagram attached to unit access panel.)
Check all electrical connections, including
factory wiring within the unit and make sure all
connections are tight.
DO NOT connect aluminum field wire to the
contactor terminals.
Grounding
WARNING: The unit must be
permanently grounded. Failure to do so can cause
electrical shock resulting in severe personal injury
or death.
A grounding lug is provided near the line-voltage
power entrance for a ground wire.
